Did I Break Something????

[jpx8080]

Hello all, I'm new to the forum. I'm Paul from NJ and I'm active duty in the US Coast Guard.

I've searched all over trying to find the answer to this but I heard that you guys are the people to ask.

This is a Mercruiser 3.0 Alpha One on a Stingray 190 RS (1998):

I was out fishing today and had 2 people aboard who were getting sick. I don't like to head in at low tide because the ramp I use in the bay is extremely shallow but I felt bad for them. I ended up heading in.

There is a lot of black mud at the dock and I started churning it up (I was only making headway speed). I put the boat in neutral and it stalled.

The ignition fuse blew. I ended up going through 3 fuses over the next hour.

I got back to the dock and got the boat out and home. Replaced the fuse again at home and started flushing the motor with freshwater. All seems fine now. I ran the motor for about 45 mins total with freshwater.

Seems weird. Is this even related to the mud? Is something else wrong? This boat has been maintained extremely well and only has 158 hours on it.

Thanks if anyone can help.

Did the fuses only blow when you put it in neutral???

Did the ignition fuses blow while cranking for start? Maybe you got a bunch of wet mud in the cooling system and it stalled from water pump mud load while idling. That's only a guess, but it's a possibility.
If that is any possibility I'd pull all the components you would pull for a winterization and rinse them. Also you are possibly in for an impeller, check it while running in water. The hose pressure on muffs won't show up a bad impeller.

They did only blow in neutral (after having the outdrive clutched in and I dropped it into neutral the ignition fuse went every time after the mud).

I'd replace the fuse and could start it right up. Nothing happened back at home with the muffs and the temp never went up that I noticed either.

I might have to check out the impeller now too.
